From 64850ca4f7dc2ca0fdb21d078d93cd636de5c87a Mon Sep 17 00:00:00 2001 From: Niklas Haas Date: Sun, 23 Feb 2014 15:37:13 +0100 Subject: Lower precedence of equality constraints This drops them to the new precedence pREC_CTX, which makes single eqaulity constraints show up as (a ~ b) => ty, in line with GHC's rendering. Additional tests added to make sure other type operators render as intended.
